摘要： An EDM apparatus for high speed machining of a workpiece and redressing of a graphite electrode by an ultrasonic machining tool or a total form machining tool. When the electrode becomes worn the workpiece clamped on a table (1) is shifted away by a slideway mechanism (4) so that a master on another table (2) confronts the worn electrode. The electrode is then redressed and the workpiece is slid back into position by the slideway mechanism (4) for more machining by the redressed electrode.

摘要： A process for controlling the tool infeed prior to machining a semi-machined gear comprises aligning the tool with the gear and feeding the tool radially inwardly in rapid traverse without making contact with the gear. The continuous rotating tool is then fed in incrementally in intervals of at least one gear revolution until the tool touches the gear for the first time. At this time the machining process is started.

摘要： A system for finish grinding a workpiece monitors the actual radius of the workpiece as the finish grinding progresses; feeds the grinding wheel into the workpiece at a feed rate which decreases, preferably at an exponential rate, as a desired final radius of the workpiece is approached; and terminates the feeding of the grinding wheel at the desired final radius of the workpiece. In a preferred embodiment, the grinding wheel is trued, simultaneously with the finish grinding, by feeding a truing element into the grinding wheel at a rate that varies as a function of the decreasing rate at which the grinding wheel is fed into the workpiece. The truing element is preferably advanced toward the grinding wheel at a rate which has (1) a first component corresponding to the rate at which it is desired to remove material from the grinding wheel at the truing interface and (2) a second component corresponding to the wear rate of the grinding wheel due to grinding, the second component varying as a function of the rate at which the grinding wheel is fed into the workpiece. The grinding wheel is preferably advanced toward the workpiece at a rate which has (1) a first component corresponding to the decreasing feed rate at which the wheel is fed into the workpiece and (2) a second component corresponding the rate at which material is removed from the grinding wheel at the truing interface. The wear rate of the grinding wheel due to grinding is determined from a power function relationship between the wheel wear rate and the wheel feed rate for a particular grinding operation.

摘要： A surface grinding machine wherein a tool holder is mounted on an upright feed screw which is in mesh with a rotary spindle nut. The latter is held against axial movement in the column of the grinding machine and is normally driven by a torque transmitting unit having an endless toothed belt trained over a first pulley which is coaxial with the nut and a second pulley mounted on the output shaft of an electric motor. A gear train is installed in parallel with the torque transmitting unit to prevent automatic lowering of the tool holder when the belt breaks. The gear train has a first gear coaxial with the first pulley, a second gear coaxial with the second pulley and an additional gear meshing with the first and second gears. The tension of the belt is monitored by a detector which transmits a signal when the belt breaks, and such signal is used to immediately arrest the motor.

摘要： An improved grinding method and apparatus is advantageously used to sequentially grind the pins of a crankshaft. During the grinding of each crankpin, the pin is supported by a steadyrest. During an initial grinding operation, the crankpins are measured or gauged to determine if they are out-of-round by an amount which is greater than the tolerances for the finished crankshaft and less than a maximum amount. If a crankpin is out-of-round by an amount which is equal to or greater than a maximum amount, the crankshaft is rejected. However, if a crankpin is out-of-round by an amount which is less than the maximum amount and more than the tolerances for a finished pin, a second grinding operation is initiated after the initial grinding operation has been completed. During the initial and second grinding operations, a main drive motor is effective to press the steadyrest against the crankpins. A secondary drive motor is provided to adjust the position of the steadyrest to compensate for the smaller size to which the crankpins are ground during the second grinding operation. The finished crankshaft is removed from the grinding machine only after both the initial and second grinding operations have been completed. When the number of consecutive out-of-round crankpins and/or crankshafts becomes excessive, a control signal initiates shutting down of the grinding machine and the establishing of an alarm to prevent the grinding of a large number of out-of-round crankshafts.
摘要翻译：改进的研磨方法和设备有利地用于顺序研磨曲轴的销。在每个曲柄销的磨削期间，销由一个稳定支架支撑。在初始研磨操作期间，测量或测量曲柄销以确定它们是否不圆度大于成品曲轴的公差并小于最大量。如果曲轴销不合适的量大于或等于最大值，则曲轴被排除。然而，如果曲柄销不合适的量小于最大量并且大于成品销的公差，则在初始研磨操作完成之后开始第二研磨操作。在初始和第二次研磨操作期间，主驱动马达有效地将稳定器压靠在曲柄销上。提供二次驱动电机以调节稳定器的位置，以补偿在第二次磨削操作期间曲柄销被磨削的较小尺寸。仅在初次和第二次研磨操作完成后，才将完成的曲轴从研磨机中取出。当连续不完整的曲柄销和/或曲轴的数量变得过大时，控制信号开始关闭磨床并建立报警器，以防止磨削大量的外圆曲轴。

摘要： In a grinding machine, a grinding wheel is digitally fed toward a workpiece being supported by a rest apparatus. Means is provided to measure a diametral dimension of the workpiece during a grinding operation. A taper amount of the workpiece ground under the support of the rest apparatus being positioned at its advanced position is calculated at the time when the measuring means generates a signal for finishing a grinding operation on the workpiece. An advanced position of the rest apparatus is compensated for a next grinding operation in response to the calculated taper amount.

摘要： A feed amount setting device for a machine tool is provided wherein an axially slidable follower rod is urged to contact a plate cam rotated by a feed device of the machine tool and is formed with an operating face for pivoting a lever arm, such that movement thereof is transmitted to a switch actuation plunger in a predetermined magnification ratio. A lever support carrying the lever arm is adjustable in a direction parallel with the follower rod, and the plunger is formed with a flat face extending in parallel relation with the adjusting direction of the lever support for engagement with the lever arm, so that the feed amount of the feed device, depending on a signal from a switch element, is variable without adjusting the mounting position of the switch element.
